A comprehensive introduction to TanStack Query for React developers, starting from the problems with manual data fetching using useState/useEffect and building up to advanced patterns. Covers core concepts like the shared cache, query keys, retries with exponential backoff, AbortSignal for request cancellation, conditional queries with enabled and skipToken, staleTime vs gcTime, and scaling patterns including queryOptions over custom hooks, domain-grouped query files, OpenAPI code generation with Orval, useQueries for dynamic parallel fetching, useInfiniteQuery for pagination, and batching invalidations to prevent UI flicker during concurrent optimistic updates.
